I would prefer to have a new private _PyObject_CAST_CONST() macro rather than casting directly.
I prefer macros because maybe tomorrow we might be able to check if the pointer is valid PyObject in debug mode. Maybe using _PyObject_CheckConsistency().
Would you mind to move these changes (add the macro and modify Py_IS_TYPE to use const) into a separated PR?

Sure, I'll make two separate PRs.

This finishes up the conversions to using Py_IS_TYPE for checking object types.
It also updates Py_IS_TYPE(ob, type) to be able to take a const objects and a const type.
